Dbeaver is

Free multi-platform database tool for developers, database administrators, analysts, and all people who need to work with databases. Supports all popular databases: MySQL, PostgreSQL, SQLite, Oracle, DB2, SQL Server, Sybase, MS Access, Teradata, Firebird, Apache Hive, Phoenix, Presto, etc.

Has a lot of features including metadata editor, SQL editor, rich data editor, ERD, data export/import/migration, SQL execution plans, etc.

Like I said It is a hidden gem for the developers then I mean it. Dbeaver has vast support for database connectivity. You can connect any database literally what you think of.

It downloads and installs relevant database drivers when you connect any new type of database for the first time and it is one of the reasons it has less installer size and occupies less disk space even after installation despite the fact that it supports many databases.

Bonus Points:

• It is open-sourced
• Releasing new features and bugs fixes immensely.
• Supports all OS - Mac, Windows, Linux
